Hello. I from Russia also do not promise that my English will be good. I have faced one problem, but one person has advised to address here for the help. When I play a mode of galactic war, sometimes at fight start there is an eternal loading of system if to press a certain part of the screen game is switched off and there is an error: "The program "pa.exe" does not work". I ask to help me with this problem, in advance thanks.
You should update your drivers, even though they're not very old they can cause problems. Although your GPU is so old that i'm not even sure if they have more current drivers. Yeah i just checked, they dont have any newer drivers. Do you use anything on this list? http://steamcommunity.com/app/233250/discussions/2/558751813508748383/
Could you try disabling the virus scanner completely as a test and see if that helps? Another thing you may wish to try is to increase the amount of virtual memory. You only have 4 GB of RAM, which is the minimum for PA, so you are going to need a decent amount of virtual memory to compensate. It's currently set to 6 GB, and I would suggest increasing it to at least 14 GB. Instructions on how to do so are here: http://windows.microsoft.com/en-us/windows/change-virtual-memory-size#1TC=windows-7
